To IZZ whom it may nonoern lie itknown that 1'. Ti ms MURRAY, 2i ritizenof the United Sit-lie residing at New York. in the oounty oi h ow York and 5 hit-ate of New York, have inventod a cnrtain new and useful Improvementin Protective U. gs for Linc Conduchns, of which the roilowing is specification.

The invention is a tubular sheet metal oasi'or line oonduciors. and is espscially nod to protect hon-.1 wiring. when he sonar is carried along the surfaces of Walls. i H etc. The construoiion is such as to mil, ens-1y access to rho conductors, at any poin, to prevent. lire or moisture reaching tl'nsm, and to prosen'ta sighsiy appearance. 3%. in fact the casing may be used, if ed. as a molding member on ceilings or is 2 In ho accompan ing drswings=--Figuro l :2 plan View 0 my z-ococtive-casing. i is a scctionai View on i-HC nnc .0, of

portions of the flange. The Width of the strip between the flanges is to be sufficient to accommodate the line wires to be incloscd. The cover (1 is integrally formed of a similar strip of resilient sheet metal, and has longitudinal side flanges I nroduced by bonding said strip. Th6 Width of the cover is to be such that when it is placed upon the base portion B, the side flanges I will lap over and press inwardly the bent over portions of the flanges E, so that the spring action of said flange E will hold said cover nu ly in place. The flanges I may be inclinsu toward one another so as to secure closer engagement with said flanges E. When the cover 0 is in place on the base portion B, its under side rests on the outer bonds (:l of flanges E, and its flanges I extend nearly to the bottom of the gutters H. .i'n said gutters are openings for the screws J, by -Which the device is attached to the wall, ceiling or other support.

In joining the casing to an outlet block, as K, of any suita le construction, the end of the base portion B is brought into contact with said block, and the cover is cut away to permit of the line Wires L being led into the usual block openings. In. order to cover this opening in the cover, as well as said short supplenieniary cover M, Fig. 6, having side flanges N, similar to the flanges I on cover (I, and having one end of enlarged cross sectional as shown at O. This cover is made enough to be received upon the end portion of cover C in proximity to block K.

in using the device, the sections of the base portion B are secured in proper position on the Wall, ceiling or other support, by

the screws J, and the outlet blocks or other fixtures to which the wires are to be led are also fixed in place. The line Wires are then laid in said base portions and attached to the fixtures. The covers C are then an plied, and Where needed the supplementary co ers M are: adjusted in position. If desired, auxiliary covers M may be made without the enlargomout at the end, and used to cover the joints between the sections of the casing, as shown at P, Figs. 1 and 2. The line wires are thus incloscd in a moistureproof protective metal casing, and yet are easily acoossiblc at any point or'along their entire length, by removing the proper cover section, or such sections as may be necessary.

As the covers are secured without any extraneous iasttnlngs, their removal and application is easily accnni 'ilislietl. \Vlien tin: llijVlCt} n attatrlietl to a ceiling or side walls; the nut-tin'iml of the gutters H aml tliv flange-s fmin barriers n1" dams to the entrant-e of moisture i'rnin Ailing or walls tn the interim of tiiu (fztSll'lQ.
